WHEEL-PLOW.

SPECIFICATION forming part of Letters Patent No. 425,592, dated April15, 1890.

Application filed January 8, 1890. Serial No. 336,272. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH O. BOUGHNER, a citizen of the United Statesof America, residing at Paris, in the county of Bourbon, in the State ofKentucky, have invented certain new and useful Improvements in \VheeLPlows, of which the following is a specification.

My invention has relation to improvements in wheel-plows, and the objectis to provide a plow of the character and class named which may bereadily adjusted as to the depth of the furrow by changing the height ofthe carriage in its relation to the wheels, and also to provide improvedmeans whereby the plow is relieved from the efiects of its contacts withimpediments in its course and easily released from such contact withoutbacking the team and carriage.

I attain the object of my invention by the means illustrated in theaccompanying drawings, wherein- Figure l is a side view of the plow, thewheel being removed. Fig. 2 is a plan view. Fig. 3 is a longitudinalsection on the line a; a: of Fig. 2, showing a segment of the swingin gframe, its supports, and the lever and 0011-.

necting-rod in side view. Fig. 4 is a detail of the foot-lever whichlooks the swinging frame in position. Fig. 5 is a perspective of theaxle and adjusting means. Fig. 6 is a perspective of the swinging frameremoved from the carriage, showing the plow attached thereto.

A designates the carriage-frame, made of substantial stuff of such sizeand strength as may withstand the strains to which it will be subjectedand to meetthe purposes of tillage. This frame is composed of sidepieces 1 2, connected at the front and rear by top and bottomcross-pieces 3 4 5 6. To the under side of the said pieces of the frameare secured boxhousings, consisting of the inner piece 7 and side pieces8 9, having inward-projecting flanges 10, leaving the outer side openand forming a housing for the vertically-arranged portion of the axlesto slide in. The axles consist of a short arm having spindles 11,carrying the wheels, and vertically-arranged sliding boxes 12, havingrabbets 13 in their outer corners to engage the flanges of the housings.These sliding boxes have a hole formed through them from top to bottom,and in this is arrangeda threaded nut 14,1et in by means of a mortise15, forming a seat for the nuts.

Through the side pieces of the frame are projected lifting-screws 16-17,having keepers or washers 18 19 above and below the side pieces, whichkeep the stems of the lifting-screws from moving up ordown when they areturned by means of the handles 20 on their upper ends. The lower partsof the lifting-screws are provided with threads 21, which engage thenuts in the sliding boxes.

The keepers 18 are formed with steps 22, which are engaged by a pawl 23,mounted on the side pieces, and serve to hold the lifting screws infixed vertical position. By turning the lifting-screws up or down acorresponding movement is given to the sliding boxes carrying the aXleand wheels, and the carriage is thus adjusted to any desired height.

On the inner side of each side piece of the carriage, at near each endthereof, are secured arms 24 25, arranged to project downward and atinclines, as shown. In these arms are formed ways 26, having their lowerend walls formed to correspond to the curvature of the segments of theswinging frame. These ways serve as seats and guides for the segments intheir movements. In bearings 27 28 on the carriage is mounted a shaft29, having fixed thereon two lever-arms 3O 31, to the lower ends ofwhich are connected rods 32, which extend back and have their endsattached to the segments of the swinging frame. To the top of one of thelever-arms, as 30, is fixed a lever 33, extending back, as shown, whichenables the operator to shift the swinging frame from the rear of thecarriage.

B designates the swinging frame. This consists of two segments of acircle 34 35, lodged in the ways 26 of the arms 24 25. These segmentsare connected at their forward end by a cross-piece 36, have across-piece 37 forward of the middle of their are to hold the clevis endof the plow-beam, as shown at 38, and at the rear end the segments areconnected by a cross-piece 39, which supports and steadies theplow-beam. It will be observed from the foregoing description that bymoving the segments the plow necessarily moves with them.

0 designates the plow, of which there may be two, if desired, one onlybeing shown in the illustration. The end of the plow-beam is providedwith'a clevis, as shown, which is connected to a clevis 40 on thecross-piece 37, and the rear end of the beam is secured to thecross-piece 39 by means of hooks 41, having threaded stems, a keeper-bar42, and nuts 43.

D designates the tongue, having its rear end extended the length of theframe, as shown, and detachably secured between the cross-pieces bymeans of bolts 44 45. On the frame is a seat-support and brace-piece 46,having arranged thereon the drivers seat 47. On the tongue is pivoted afoot-lever 48, having a downward-projected arm 49, arranged to engagebehind the cross-piece 36 and formed with a foot or hand piece 50,arranged conveniently to the driver. A keeper 51 may be arranged on thelever 33, which aids in keeping the swinging frame in position.

The operation of the plow is as follows: The carriage being adjusted bymeans of lifting-screws to such a height as to'suit the team and thedepth of the furrow, the foot-lever on the tongue is dropped intoholdingposition, and the plowing may begin. In case the plow strikes anobstruction and stops its progress the foot-lever is lifted out of itsengagement behind the cross-piece of the swinging frame, which leavestheswinging frame carrying the plow to bemove'd' backward by the lever33, which 'operatio'n not only carries the plow back and out of contactwith the obstruction, but also lifts it up free to be moved over theobstruction. After the plow has been released from the obstruction theswinging frame is moved forward, the foot-lever arranged to again holdthe frame in position, and the plowing resumed.

Having thus legally described my inven 'tion and explained the principlethereof and the mode of applying that principle so as to ing frame B,having curved segments ar ranged in said ways, and a lever on thecarriage to move the swinging frame, substantially as and for thepurpose specified.

2. In a wheel-plow, the combination of a ,frame provided withdownward-projecting arms having ways 26 formed therein, a swinging frameB, having curved segments arranged in said ways; a lever on the carriageto move the swinging frame, and a leverto lockthe" swinging frame in afixed position substantially as and for the purpose specified.

3. In a wheel-plow, the combination or a carriage-frame provided withdownward-projecting arms 24 25, formed with ways 26, the

swinging frame B, having curved segments 34 35 arranged in said ways,ash'aft 29,-1nonnted on the carriage-frame, le'vei -a'rrns on the shaftconnected to the segments, and aplow secured to cross-pieces of theswinging'frame, substantially as described.

4. In a Wheel-plow, the combination of the carriageffaine, the swingingfrafne arranged under the carriage-frame andcarrying the plow-beam, thetongue on the carriage-frame, and a foot-lever pivoted to the tongue andprovided with a downward-projecting arm to engage the swinging frame andloc'kit in forward position, substantially as described.

In witness whereof I have herenntoset my hand in. the presence of twoattesting witnesses. p
